AIR-COMPRESSOR.

SPECIFICATION forming part of Letters Patent No. 686,784, dated November 19, 1901.

Application tiled May 7,1900. A'Serial No. 15,764. (No model.) I

To all whom t may concer-m Be it known that I, JAMES P. TRYNER, a citizen of the United States, residing at Pueblo, in the county of Pueblo and State of Colorado, have invented new and useful Improvements in Air-Compressors, of which the following is a specification. v

This invention relates to new and useful improvements in air-compressors especially adapted for inflating vehicle-tires; and its primary object is to provide a device of simple and inexpensive,construction which is adapted to operate automatically under ordinary water-pressure.

To this end the inventionconsists in providinga cylinder of any desired form and material, connected at theV bottom thereof to a water inlet and outlet which are adapted to be opened and closed automatically and alternately by means of a receptacle pivoted to one end of a weighted lever which has its bearing at the center, said receptacle being connected, by means of flexible tubes, to the top and bottom of the cylinder and to the storage-reservoir. An air-inlet is provided for the cylinder, and a valve of peculiar construction is arranged within the lower flexible connecting-tube and is for the purpose hereinafter more fully described.

The invention also consists in the further novel construction and combination of parts hereinafter more fully described and claimed, and illustrated-in the accompanying drawings, showing the preferred form of myinvention, and in which` Y Figure 1 is a view, partly in section and partly in elevation, showing the lever of the compressor at one end of its stroke; and Fig. 2 is a similar view showing the lever at the opposite end of its stroke.

Referring to said figures by numerals of reference, 1 is a cylinder of ordinary construction and material, and connected to the bottom thereof is a pipe 2, having a four-Way valve 3 connected thereto by means of pipes 4, and leading to this valve are a supply 5 and a discharge 6, as shown. The valve 3 is formed of a casing having a partition 7 in the center thereof and an upwardly-extending rod 8 therethrough, which rod is provided with plates 9 thereon, which are adapted to register alternately with the openings 10 within lfrom the pipe 2, as shown.

the casing of the valve. l The rod 8 is provided near its end with knobs or projections 11, which are arranged at a suitable distance apart. A baud 12 is preferably secured around the cylinder l, and this band is provided With a lug or extension 13, upon which is pivotally mounted a lever 14, which is engaged bya weight 16, which is "suspended therefrom. Near the vopposite end of said lever are two extensions 17, between which is mounted the rod 8, said lever lying between the knobs 11. A lug 19 is secured to a pipe 20, extending upwardly from a receptacle 21. The lever 14 has a hook 15 at the end thereof, which is elevated out of alinement with the lever and is adapted to engage the weight 16, before referred to. A ring attached to lug 19 enters the hook the same as at 15. The receptacle is of any desired form and is lighter than the weight 16 and is therefore held normally in a raised position. The pipe 2O thereof is connected, by means of a yflexible tube 22, with a pipe 23, which is connected to the upper end of the cylinder 1 and is provided with a suitably-valved inlet 24. A secondpipe 25 extends from the upper end of the receptacle 21 and is connected, by means of a fiexible tube 26, with a suitable air-reservoir. (Not shown.)

Extending downward from the receptacle 21 is a short pipe 27, connected, by means of a flexible tube 28, to a pipe 29, which extends This pipe 29 is provided with a valve 30 therein, which opens outward from the receptacle and is for the purpose hereinafter more fully described.

In operation, presuming that the apparatus is partially lled with water, as shown in Fig. 2, the rod 8 will be held .in raised position by means of the weighted lever 14, as shown in said figure. When the rod is in this position, the valve 9 within the supply portion of the casing 3 is open, while the dischargevalve within said casing is closed, as shown. Water will enter from the supply-pipe 5 to the pipes 4 and 2 and into the cylinder 1, as is obvious. Said cylinder will be gradually filled, and the air therein will be forced upward and through pipe 23 and flexible tube 22 into the' receptacle 21 and thence out through the pipes 25 and 26 into the reservoir, the downward passage of the air from IOO the pipe 28 being prevented by the waterpressure within the pipes 2 and 29, as is obvious. Pipe 25 has a check-valve through which the air passes to the reservoir and is prevented from returning into receptacle 21. After the cylinder 1 has been filled by the water admitted thereto the same will iiow outward through the pipes 23 and 22 into the receptacle 21, and when said receptacle is filled the weight thereof will overbalance the weight 16 upon the opposite end of the lever, causing the receptacle to drop into the position shown in Fig. 1, and thereby bringing the lever 14 into contact with the lower knob 11, forcing the rod 8 downward, and closing the supply and opening the discharge pipe.,

It is obvious that the water will flow direct der 1 is empty, when valve 30 will open and allow the discharge from receptacle 2l into the pipe 2 and out through the dischargepipe. When a suitable amount has been dis- I charged from the receptacle 21, the same w-ill be overbalanced by the weight 16 and thrown upward, thereby carrying the rod S therewith and opening the supply and closing the discharge, when the operation hereinbefore described will be repeated. It will be seen that while the water is being discharged from the cylinder 1 and the receptacle 2l air will be drawn thereby through the inlet 24 into the cylinder 1, and the valve within this inlet is so arranged as to prev-ent the outward flow of air therethrough.

In the foregoing description I have shown the preferred form of my invention; but I do not limit myself thereto, as I am aware that modifications may be made therein without departing from the spirit or sacrificing the advantages thereof, and I therefore reserve the right to make such changes and alterations as fairly fall within the scope of my invention.

I-Iaving thus fully describedmy invention, what I claim as new, and desire to secure by Letters Patent, is
